Abstract
A data converter and an impedance matching control method are provided. The data converter includes a comparator, a capacitor array as well as a switch and impedance matching circuit. The comparator includes a first input terminal and a second input terminal. The capacitor array includes a plurality of capacitors, and a first end of each capacitor is coupled to the first input terminal or the second input terminal. The switch and impedance matching circuit is coupled to a second end of a target capacitor among the capacitors and configured to couple the second end to a first reference voltage or a second reference voltage according to a control signal and adjust an impedance according to an impedance adjusting signal, in which the impedance is the impedance of the switch and impedance matching circuit. The first reference voltage is different from the second reference voltage.
